It’s been seven months since Britney Spears and Jason Trawickcalled off their engagement, and while she’s moved on, it looks like he still needs some help in the dating department! The Hollywood manager attended the Delta Air Lines Summer Celebration on Aug. 16 where he hit on and got completely shut down by Shameless star Emmy Rossum.

“Emmy was dancing alone in front of the DJ booth at the party while Jason was eyeballing her body up and down from across the room while licking his lips and smoking a cigarette!” an onlooker tells Star. Eventually, Britney’s ex made his move, telling the actress that he liked her dress and that she had “great moves.”

Unfortunately, his pick up line didn’t work so well. “Emmy laughed uncomfortably, obviously having no idea who he was,” our witness reveals. “She said ‘Thank you’ and immediately walked away with her girlfriend, leaving him standing alone and clearly embarrassed. You could tell she was just not into him — at all.”

While Emmy enjoyed the rest of the night, Jason got discouraged by the diss. “He knew he failed miserably,” the onlooker explains. “It was a sad sight to see.”
